HOISTING DEVICE.

Specification of Letters Patent.

Patented Apr. 25, 191%.

Application filed May 22, 1914. Serial No. 840,279.

To all whom it may concern:

Be it known that l, LovINE O. BERG, a citizen of the' United States,residing at Letcher, in the county of Sanborn and State of South Dakota,have invented certain new and useful Improvements in Hoisting Devices,of which the following is a specification.

My invention relates to improvements in hoisting devices, and moreparticularly to an improved and simplified grain hoist.

As its primary object, the invention contemplates a device wherein asectional bucket or receptacle is so constructed as to be utilized inone arrangement as a receptacle for the grain, and in anotherarrangement as a chute or conveyer, the latter arrangement providing fora discharge of the receptacle or bucket contents into a suitable bin orreceptacle arranged at one slde of the bucket preferably at a polntremote therefrom.

As a further object, the invention contemplates means, such in itsnature, as to provide for the raising and lowermgof the bucket orrecptacle, means also belng provided whereby movement of the dischargechute may be easily controlled from a point upon the ground, the bucketor receptacle having been raised or elevated to the desired degree. i

The above and additional objects are accomplished by such means as areillustrated in their preferred embodiment in the accompanying drawings,described in the following specification, and then more particularlypointed out in the claims which are appended hereto and form a part ofthis application.

In describing my invention in detail reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure'lis a side elevation of a gram hoist constructed in accordance with thepresent invention, the dotted lines indicating the position of thebucket as the contents thereof is being discharged; Fig. 2 1s a sideelevation of the bucket or receptacle, the chute or movable bucketsection having been thrown into operative position; and

Fig. 3 is a top plan of the bucket or receptacle as illustrated in Fig.2.

Before proceeding with the description of the drawings, I desire to callparticular attent on to the fact that whilel have evolved my inventionwith reference to its applicatlon in connection with the hoisting ofgram, the same may be readily utilized as a holstmg device for variousarticles of merchandise capable of being discharged in a manner apparentupon a continued reading of the descriptive matter relating thereto.

Referring now to the drawings by numorals, and to illustrate theapplication of the invention, 1 designates a barn or warehouse into theloft of which the grain or other material acted upon is to be stored. Aloft door or opening 2 is formed in the sides of the barn 1, said doorhaving ar-.

ranged directly thereover a beam or support 3 from which the devicecomprising my present invention is suspended.

The grain bucket or receptacle, designated as an entirety by the numeral4: is

suspended from the beam or support 3 by means of a rope or like flexibleelement designated 5, said rope being attached at one end to a pulley 6mounted to slide longitudinally of the beam 3 from which point itdepends, as illustrated in Fig. 1 to be arranged over a second pulley 7carried by the bucket or receptacle 4. From the pulley 7 ,the ropeextends upwardly again to the pulley 6, passing thereover and dependingto a point upon or adjacent the ground, from which point the said ropeis operated to provide for a raising and lowering of the bucket orreceptacle in a manner common to the art. Said b ucket or receptacle inits preferred embodiment is composed of a pair of bucket sectionsdesignated respectively 8' and 9, the latter being movable relatively tothe former and hinged as at 10 to the said section 8 in a mannerapparent in Fig. 2. Section 8 is so formed as to provide, when suspendedor elevated, a sloping floor or bottom, the sides of the said section 8converging from one end toward the hinge point 10 to provide for theretention of a predetermined quantity of grain or the like therein.Section 9, when moved into the position indicated in Fig. 1,

ment 11 secured at one end to the said sec-v tion 9, said rope orelement being arranged over a pulley 12 carried by pulley 7 from whichpoint it depends to an extension-13 of the section 8, passing through anopening 14 of the said extension and depending therefrom to a point uponor adjacent the ground.

If desired, a knot 13 may be made in the rope 11, said knot, whensection 9 of the bucket is opened, abutting the extension 13 of section'8 to in this manner limit movement of section 9 and. hold said sectionalined with the floor or bottom of section 8, the said section 9 whenthus positioned forminga chute from'whic'h the grain is discharged.

As a means whereby movablesection 9 is forced outwardly or away fromsection 8 when it is desired that the said section 9 be used asadischarge chute, I provide a spring 14 abutting atone end a strip 15extending transversely of section 8 and at .its opposite end the head-16of a pin, bolt or the like 17 movable relatively to said strip 15, saidbolt or pin forming an abutment for the said movable section 9,thelatter, of course, be ing closed. In addition to the pressure broughtto bear upon section 9 by the tension of the "said spring 14, the weightof the grain within the' receptacle being directed, by reason of thesloping bottom, upon the said movable section will provide for anautomatic opening of the latter, the moment element 11 is slacked.

.Receptacle or bucket't is suspended from pulley 7 by means of ropes 18attached to both the pulley and, the receptacle and to the pulley and anextension 19 at the converged end of the receptacle. The side walls ofthe bucket section 8 converge toward the chute or movable section 9 todirect, in a discharge operation, the contents thereof onto the chute.

()peration of the device is as follows Receptacle 4 is firstfilled withgrain, movable section 9 being closed against tension of spring 14 andso held by drawing rope 11 taut. After having been filled, bucket orreceptacle is raised through operation of rope 5 into the-positionindicated in dotted lines of Fig. 1, in which event, said rope 11 isslacked, permitting, by the weight of the receptacle contents andthe'tension of sprlng 14' movable section 9 to open or swing from hingepoint 10 into the position illustrated in FigJQ, in which event, saidmovable section 9 is alined at an inclination with. the sloping floor orbottom of section 8 thus forming a chute onto which the receptaclecontents is'directed by the converging walls and sloping bottom, saidchute discharging the gram into a bin or receptacle (not shown) arrangedat one side of the loft prefagaindrawn taut thereby permitting movablesection 9 to close, and, by lowering the entire bucket, the device isagain ready to be a second time filled and elevated in the manner aboveset forth.

From the foregoing, taken in connection with the accompanying drawingsit is apparent that the person operating element 11 not only controlmovement of section 9, but also, during a raising of the bucket holdsthe latter against turning and swinging against the side of the barn orother structure in connection with which the device is used; that thesaid section 9 automatically opens the moment element 11 is slaeked; andthat when opened, said movable section 9 is alined with the slopingbottom of section 8 and, by reason of its novel formation, effects thedischarge chute or trough onto which the grain acted upon is directedand from which it is discharged.

In reduction to practice, I have found that the form of my invention,illustrated in the drawings and referred to in the above description, asthe preferred embodiment, is the most efficient and practical; yetrealizing that the conditions concurrent with the adoption of my devicewill necessarily vary, I desire to emphasize the fact that various minorchanges in details of con struction, proportion and arrangement of partsmay be resorted to, when required, without sacrificing any of theadvantages of my invention, as defined in the appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

1. In a hoisting device, a receptacle having a discharge opening formedtherein, a discharge chute hingedly connected to the said receptacle ata point adjacent said opening, a spring abutment mounted on thereceptacle, means operable to maintain said chute in a vertical positionand in engagement with said spring abutment to form a closure for saidopening, said spring abutment operating automatically upon a release ofsaid last mentioned means to move said discharge chute into a positionalined with the base 'of the receptacle whereby' to form a continuationthereof, as andfor the purpose set forth.

2. In a hoisting device, a receptacle having a discharge opening formedtherein, a discharge chute hingedly connected to said receptacle at apoint adjacent said opening, a yielding abutment mounted on saidreceptacle for engagement with said discharge chute when moved to aposition closing said opening, a means to move said discharge chute intothe position stated, said abutment operating automatically to removewith said receptacle whereby to form a continuation of the body thereofat the opening therein, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
